Methods of combined bioprocessing and related microorganisms， thermophilic and/or acidophilic enzymes， and nucleic acids encoding said enzymes

A genetically modified organism comprising: at least one nucleic acid sequence and/or at least one recombinant nucleic acid isolated from Alicyclobacillus acidocaldarius and encoding a polypeptide involved in at least partially degrading， cleaving， transporting， metabolizing， or removing polysaccharides， cellulose， lignocellulose， hemicellulose， lignin， starch， sugars， sugar oligomers， carbohydrates， complex carbohydrates， chitin， heteroxylans， glycosides， xylan-， glucan-， galactan-， or mannan-decorating groups; and at least one nucleic acid sequence and/or at least one recombinant nucleic acid encoding a polypeptide involved in fermenting sugar molecules to a product. Additionally， enzymatic and/or proteinaceous extracts may be isolated from one or more genetically modified organisms. The extracts are utilized to convert biomass into a product. Further provided are methods of converting biomass into products comprising: placing the genetically modified organism and/or enzymatic extracts thereof in fluid contact with polysaccharides， cellulose， lignocellulose， hemicellulose， lignin， starch， sugars， sugar oligomers， carbohydrates， complex carbohydrates， chitin， heteroxylans， glycosides， and/or xylan-， glucan-， galactan-， or mannan-decorating groups.
